This is what the QR code on a battery resolves to. The public resolver serves the same passport two ways: JSON at /p/{uniqueIdentifier} and JSON-LD at /p/{uniqueIdentifier}.jsonld (or the same URL with Accept: application/ld+json). Point at any property to see which EU data point it carries and who may see it.

JSON and JSON-LD

Both carry a weak ETag and are cacheable; an unknown or unpublished identifier answers 404, a recycled battery’s passport 410. The JSON-LD context is a minimal Battery-Pass-style vocabulary that will be replaced by the semantic model the Commission publishes.
What is public
Only Annex XIII Point 1 values reach the resolver, and only those that are set. Data points marked N/A for every category in the EU guidance (such as the repeated material composition) are never shown, even when stored. Points 2 to 4 — detailed composition, dismantling information, test reports, state of health — stay on the server and are readable only with your own key through GET /passports/{id}. The field catalogue lists every Point 1 field.
